I have several DOS games that run in VGA mode but the spacial resolution is less, more like 320x200. My AGP card scales this up to 640x480. I am using a real CRT monitor but was wondering if it's possible to skip every other line in software so each physically drawn scanline on the screen corresponds to its own line of pixels from the game, instead of being line doubled. I have done this with photoshopped screenshots opened within Windows at 640x480:
